Developmentof high performance oilseparator for improvement of heat exchanger efficiency

本研究探讨利用油雾带电的库仑力分离油以减少制冷剂压缩机的供油量的可行性。在制冷剂气氛中，虽然电晕放电的起始电压随着压力而增加，但是油滴可以通过电晕放电充电并通过库仑力分离。当施加感应电荷以对液滴充电时，可以在较低电压下分离液滴。据观察，具有大极性的油如PAG油通过电场中的极化而变形。

This study examined feasibility of an oil separation by Coulomb force with electric charge of oil mist in order to decrease an oil delivery from a refrigerant compressor. In the refrigerant atmosphere, although an inception voltage of Corona discharge increases with pressure, the oil droplet can be charged by the Corona discharge and separated by the Coulomb force. When an induction charge is applied to charge the droplet, it can be separated at lower voltage. It is observed that oil having large polarity such as PAG oil deforms by polarization in the electric field.
